That’s nothing to sneeze at !I actually average 41-42 mpg and have seen as high as 52+ mpg local driving between 35-50 mph in my 6 speed.
My 11mpg 4x4 quigley van now sits on fair weather days . RIP (rust in peace)LOL. But when the central PA winters roll around , that fuel sucking beast serves its purpose well .Our Smart "Asst" ( the vanity plate) is a great commuting tool.
So are the old Benz Diesel wagon and the beastly big Ford F-350.
The Smart has really improved our fuel budget now that the other rides don't have to everything.
